Fit-for-Purpose Platform

WSO2 Carbon Platform

● WSO2 Carbon is a○ lean, ○ modular, ○ enterprise-class middleware platform.

● All WSO2 middleware products are build on top of Carbon

■ Application Server, Enterprise Service Bus, Identity Server, Business Process Server, API Manager..

● Offers a wide-range of reusable core components to middleware products.

■ Security, Clustering, Caching, Logging, Monitoring, User management..

What is Carbon?

Carbon Kernel Runtime

● Modular server development framework ○ Defines how to develop modules/components in Carbon○ Defines how these modules collaborate at runtime.○ Provides a provisioning solution for the Carbon platform.

● Provides a minimal runtime for any WSO2 middleware product.○ A WSO2 middleware product can be considered as a collection of

related modules/components running on this minimal runtime.

Under the covers: OSGi, P2

● OSGi as the fundamental modularization technology in WSO2 Carbon.

● OSGi provides a better module system for Java:■ Better control than packages■ Versioning■ Dynamic loading

● Carbon Relies on Eclipse’ open source implementation of OSGi - Equinox.

● Provisioning solution based on Equinox P2○ P2 is generic provisioning solution for OSGi based systems.

Feature Provisioning in Carbon

Benefits of WSO2 Carbon

● WSO2 technology as well our customers have benefitted from this componentized middleware platform.

● Enables agile development○ Small teams focusing on their own features○ Time to market factor for product teams.

● Best of breed○ Each product brings enhancements to the core.

● No Internal integration challenges.○ Eliminated these challenges by sharing cross-cutting features

across all the middleware products ○ e.g. Security, User mgt, Clustering, Multi-tenancy, Logging

Consistency in usability

● User experience is same across all the products.

● Reduced learning curve.

● Any Carbon based product will have this directory hierarchy.

● If you are familiar with installing, configuring and operating Application server, same applies all the other products.

Composite Application model (C-App)

● Improved definition of “enterprise project”.

● WSO2 developer studio allows to package config and code of an enterprise project into a single archive. (a “car” file)

● A CAR file can be deployed to different runtimes.

● Each runtime will only deploy the artefacts which match with the role that the runtime is playing.

■ e.g. ESB runtime will not deploy a data service in the CAR file unless otherwise the default configuration is altered.

C-App

Server Profiles

● Enables a product to run in multiple modes/profiles

● A profile of a product describes the runtime behaviour.

● Each ale contains only the required set of components

○ E.g. A single API Manager distribution can play following roles.

API PublisherAPI SubscriberAPI GatewayAuth Server

● One download, multiple servers.e.g. sh wso2carbon.sh -Dprofile=profile_name

Unprecedented Extensibility

● Extensibility is provided from the heart of the Carbon platform.

● Componentized architecture allows you to enrich the rich set of features of Carbon platform.

● Certain Extensions are treated as first class citizens of the platform.

Core Platform Components

● User Manager○ User provisioning and access model○ APIs to integrate third party user stores

● Registry○ Provides repository API to store any type of data of metadata.

● Distributed Caching and Clustering○ Based use Hazelcast

● Deployment Engine○ Ghost deployment○ Deployment Synchronization and APIs to plugin any repository.

● UI framework○ Based on Apache Tiles, it provides clean API to plugin your custom UI

components.

● Data sources

WSO2 Platform Adaptability

What Carbon Platform means for your Business

● Simpler, speedier projects.

● Reduced risk of failure

● Required only few specialized consultants

● Platform evolution.

WSO2 Carbon 5 (C5)

● Next generation of the Carbon platform.

● Still at the milestone 1 level.

● Planning to release in 6 months.
